What OS was used to create the tape?

Did you use Mondo to create this particular tape?

This error looks like one that I get when I try to read a tar tape on an 
SGI machine that was created on an HP machine. To get it to work, I have 
to use a different device file (on an SGI machine, it's something like 
/dev/rmt/tps0d4ns). Not being familiar with Mondo, I don't know if tar 
can read Mondo's format. You could do an  'ls /dev/st0*' and try the 
different tape devices you find.

tar tvf /dev/st0a
tar tvf /dev/st0l     .......

but my guess is that if it's a Mondo created tape you might have to use 
something like mondorestore..... Jesse, can you shed some light on this?
